HLA-B phenotype modifies the course of Behçet's disease in Moroccan patients.

In Moroccan patients, predisposition to Behçet's disease is associated with HLA-B*51, mostly in males with young age at disease onset. In addition, the disease is associated with B*15 both in females and in males with late disease onset. We analyzed the clinical presentation, the severity and the course of the disease in 86 Moroccan patients according to their HLA-B phenotype. The presence of the B*51 or B*15 did not predispose to a particular clinical manifestation, nor to a more severe presentation of the disease. By contrast, outcome of the disease significantly differed depending on HLA-B phenotype, with an increase of symptoms in most B*51+ patients and in half of B*15 patients, and a remission or a decrease of symptoms in all B*51-B*15- patients. This variable course was mostly observed for ocular lesions, skin lesions, articular symptoms, and neurological symptoms. These data may suggest that treatment should be given early in the course of the disease in B*51 or B*15-positive patients in order to stabilize the inflammatory process.

[Kaposi's sarcoma during HIV infection in Morocco (apropos of 50 cases)].

Kaposi's sarcoma is the most common neoplasm to be found among AIDS patients. The purpose of this retrospective study is to determine the epidemiological, clinical, therapeutic features and the evolution of Kaposi's sarcoma in Moroccan patients suffering from AIDS. Between January 1987 and December 1999, 696 patients with AIDS were hospitalized in the department of infectious diseases of Casablanca. Fifty of them (7%) had Kaposi's sarcoma. AIDS was confirmed by ELISA and Western-Blot. The diagnosis of Kaposi's sarcoma was established by clinical aspect and I or by histologically study. It concerned 46 men and 4 women. The average age was 32.5 years. The homosexuality was noted in 38% of patients and the heterosexuality in 56% of cases. AIDS was revealed by Kaposi's sarcoma in 82% of cases. The Lesions were found in the skin (96%), in the skin and mucous membranes (56%), in the lung (14%), in the gastrointestinal tract (12%) and in the lymphatic nodes (8%). The average CD4 cells count was 212.8/mm3. The chemotherapy was instituted in 43 patients and the radiotherapy in 5 patients (alone or associated with chemotherapy). Four patients received HAART. Six patients didn't received any treatment. The evolution has been characterized by the death in 61% of patients. This death was due to Kaposi's sarcoma in six patients and to opportunistic infections in the others cases. Our study demonstrates the high incidence of Kaposi's sarcoma as an inaugurating event of AIDS, the severity of the visceral involvement, the limit of our therapeutic materials and the wrong prognosis of this disease.

HLA class I polymorphism in a Moroccan population from Casablanca.

We have studied the distribution of HLA-A and -B alleles and haplotypes by sequence-specific primer amplification in a sample of 100 unrelated healthy individuals belonging to both Berber and Arabic-speaking groups from the region of Casablanca in Morocco. Among the 17 HLA-A and 23 HLA-B alleles observed, the most frequent were HLA-A2 (21%), -A1 (11%), -A3 (10%), -B44 (11.4%), -B50 (9.9%), -B5(8.5%) and -B35 (6.5%). Six two-locus haplotypes were observed with a frequency above 5%: A2-B50 (9.6%), A23-B44 (7.4%), A2-B15 (6.4%), A68-B39 (5.3%), A1-B51 (5.3%) and A68-B44 (4.3%). Our data confirm that, on the basis of genetic distances, the majority of present-day North Africans from Morocco are closely related to Berbers and also to Iberians. They cluster apart from Middle-Eastern Mediterranean populations, and show greater genetic distances to Eastern and other Mediterranean populations. This study will serve as a reference for further anthropological studies, as well as studies of HLA and disease associations.

[Botulism in Casablanca. (11 cases)].

Botulism is a rare but severe disease. Whereas until 1980, only one case of botulism had been reported in our department, in 1999, a real botulism epidemic took place in Morocco. To our knowledge, it's the first outbreak of that kind in Morocco. We report here an epidemiologic and descriptive study of 11 patients suffering from botulism, admitted at the Infectious Diseases department and in the Medical Intensive Care Unit of Ibn Rochd University Hospital, from August, the 10th to October, the 1st, 1999. Clinical diagnosis of botulism was made, at the admission, on ocular signs (diplopia, ptosis), swallowing troubles and/or muscle weakness. There was no fever, no trouble of conscience and normal reflexes, at the early stage of the disease. The average age of patients was of 23.9 years +/- 12.07. Three patients were first admitted in the Medical Intensive Care Unit. The period before symptom appearance varied between 7 and 96 hours. Dysphagia sore throat, dry mouth and dysphonia were always found in all patients, with normal conscience. The fever was noted in 3 cases, polypnea in 3 cases leading to respiratory assistance in 2 cases. Neurologic findings were dominated by ptosis and hypotonia. The search of botulism toxin B in blood was positive in 6 cases. The electromyography showed clear signs of botulism. The evolution was favourable in 10 cases. Respiratory complications were found in 2 cases and infectious complications in 4 cases. One patient died. The period of hospitalization varied between 10 to 24 days with an average stay of 15.8 days. Eating "mortadella" has been noticed in 7 patients) and investigations permitted to identify the factory of "mortadella" as well as the toxin's type B responsible for these poisoning. It appears clearly that it is important to reinforce hygiene controls. Physicians and specialists in public health must be aware of the severity of this illness, knowing that the recovery is shortened when the treatment is administered on an early stage of the disease.

HLA-B51 and B15 alleles confer predisposition to Behçet's disease in Moroccan patients.

HLA class I polymorphism in Moroccan patients with Behçet's disease has not been investigated so far. In this study, HLA-B* phenotype frequencies were analyzed in 86 unrelated Moroccan patients (45 males, 41 females) and 111 ethnically matched healthy controls. The predisposing effect of the B*51 was confirmed (30.2% in patients and 15.3% in controls, OR = 2.39, 95% CI [1.2-4.8], p = 0.015). It was mostly observed in males with young age at disease onset (OR= 5.5 [1.9-15.9], p = 0.002 compared to controls). The Moroccan BD group also presented a previously unknown association with HLA-B*15 (25.6% of patients versus 11.7% of controls, OR = 2.59 [1.2-5.5], p = 0.014), both in females and in males with late-onset of the disease. Altogether, the B*15 and/or B*51 alleles were expressed in 55.8% of patients compared to 27% of controls (OR = 3.4 [1.9-6.2], p < 10-4, Pc = 0.003). Our data indicate HLA-B effects on BD pathogenesis should be considered separately for men and women.

[Pregnancy and AIDS. Report of 9 cases].

The pregnancy at women infected by the HIV characterizes by the risk of transmission of the HIV to the child. The goal of this retrospective study concerning 9 deliveries of women infected by the HIV cured in the Infectious Diseases Service and the Lalla Meryem's Maternity of Casablanca CHU Ibn-rochd during 10 years (1990-1999) is to specify the experience of two services of concerning plug in cost of the patients infected by HIV by trying to pull some a protocol of plug in cost. The antiretroviral therapy has been used in 8 cases out 9. The AZT long protocol has been used in 6 cases and the bitherapy in 2 cases. The delivery has taken place by the natural way under cover of AZT in all cases. All babies have received the AZT in syrup and none has been breastfed to the breast. Two newborns on 9 out 9 have been contaminated by the HIV.

[The Sidi Frej maristan at Fez].

Sidi Frej's maristane or Fez maristane is Marocco's main and famous maristane. It is Mérinide dynasty's maristane; its rising, apogee and worse growing are close to the extent and further ruin of this dynasty. This maristane was built by Sultan Abou Youssouf Yacoub, about 1286, imitating a merinide's architectural design in shape of Spanish architecture. In another way, Sidi Frej's maristane was a pattern for many other maristanes in Marocco or in Spain. Since the XVe century, the Merinide Sultan Abou Said Othman II must sell every maristane's properties in order to fit out his troops. Then, the maristane became a mad-house. In 1943, maristane's building burnt. A Kissaria was built at the same place and patients were removed to another maristane named Sidi Frej's new maristane at Bab Khoukha.

Ceftriaxone versus penicillin G in the short-term treatment of meningococcal meningitis in adults.

Short-term treatment with ceftriaxone 2 g once daily for two days (group 1) was compared to treatment with a standard regimen of penicillin G (group 2) for six days in adults with meningococcal meningitis. Thirty-six patients were allocated in a randomized fashion to a treatment group: 16 to group 1 and 20 to group 2. The clinical and microbiological results were comparable in the two treatment groups. In both groups cultures of cerebrospinal fluid were sterile after 24 hours. One patient in each group died. In group 1 one case of fulminant meningococcemia and one case of brain abscess required further antibiotic treatment. It is concluded that short-term treatment with ceftriaxone is feasible but patients with severe forms of meningitis would not be eligible for treatment with this regimen, and careful follow-up of the patients receiving ceftriaxone is necessary.
