Prothrombotic factors in nephrotic syndrome.

Nephrotic syndrome is a hypercoagulable state with variable prevalence of clinical thrombosis. The role of platelet aggregation, fibrinogen and antithrombin III and protein S levels in the pathogenesis of hypercoagulable state in these patients is controversial. Since no study on Indians is available, the clinical and laboratory profile of 22 patients of nephrotic syndrome (age 18-35 years with an MF ratio of 4:3), have been studied. The coagulation profile revealed a prolonged APTT in 12 patients (54.5%), and a prolonged TT in four (18.1%). In the rest APTT and TT were normal. PT was raised in two patients. Fibrinogen, an acute phase reactant was raised in five patients (22.7%). Antithrombin III levels were reduced in 19 patients (86.4%), normal in one and raised in two patients. Free Protein S levels were high in 12(54.5%), normal in seven and decreased in three patients. Platelet aggregation with adrenaline and adenosine diphosphate was raised in 6 patients. Ultrasonographically detected deep vein thrombosis was seen in one patient only (4.5%) who had ATIII levels of 48%. This low incidence can be explained by elevated protein S levels which was found to be raised in 12(54.5%) cases, protein S being an anticoagulant factor. This low level of clinical thrombosis in Indian patients of nephrotic syndrome may be an ethnic variable factor. It is thus concluded that although patients with nephrotic syndrome have a hypercoagulable state, clinical thrombosis is rarely seen in Indian patients with nephrotic syndrome.

Correlation of cell counts and indices in testicular FNAC with histology in male infertility.

OBJECTIVE: To evaluate the value of percentage cell counts and cell indices in testicular fine needle aspiration cytology (FNAC) in male infertility and their correlation with histologic categories as seen in open testicular biopsies. STUDY DESIGN: Differential cell counts were performed, and cell indices, including spermatic index, Sertoli cell index and sperm-Sertoli cell index, were calculated in testicular fine needle aspiration (FNA) smears in 30 azoospermic males whose open testicular biopsies were classified as normal spermatogenesis in 10 cases, maturation arrest in 5, hypospermatogenesis in 6, Sertoli cell only syndrome in 5 and tubular/peritubular sclerosis in 4. RESULTS: In normal spermatogenesis, FNA smears showed up to 40% Sertoli cells, and spermatozoa were the predominant spermatogenetic cell type. There was a progressive increase in Sertoli cell percentage and Sertoli cell index and reduction in spermatozon percentage, spermatic index and sperm-Sertoli cell index with increasing severity of reduction in spermatogenesis in different histologic categories. The differences between mean counts and indices in normal spermatogenesis and other histologic categories were statistically significant (P < .01). CONCLUSION: The percent cell counts and cell indices in testicular FNAC correlate with histologic categories and are useful in evaluating male infertility.
